Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLVOS DE CAUCHO DE LIBRE FLUIDEZ, CUYAS PARTICULAS TIENEN UN DIAMETRO MEDIO DE 0,01 A 10 MM. CONSISTE EN ROMPER TOTALMENTE UN LATEX DE UN CAUCHO DE DIENO, DE ACRILATO O DE EPDM CON UNA TEMPERATURA DE TRANSICION CRISTALINA INFERIOR A 0 GC, MEDIANTE SUSPENSION ACUOSA DEL MISMO; INTRODUCIR EN ESTA DE UN 2 A UN 20% DE UN O VARIOS MANOMETROS DE VINILO QUE FORMAN POLIMEROS CON TEMPERATURAS DE TRANSICION CRISTALINA SUPERIORES A 25 GC; Y FINALMENTE, POLIMERIZAR EN PRESENCIA DE UN CATALIZADOR POR RADICALES. ESTOS POLVOS TIENEN APLICACIONES PARA LA FABRICACION DE ELASTOMEROS, GOMAS, MATERIALES SINTETICOS ALTAMENTE FLEXIBLES, ETC.
